Application filed November 7, 1 921. SerialNo. 513,284.

To all'whom it may corwern:

Be. lt'known that we, ROBERT K. SLAY- MAKER, GEORGE D. SLAYMAKER, and

' THOMAS Bomixn, citizens of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and usefullmpro ements in Ventilators, of which the following is a specification.

This invention relates to 'ventilators for use on vehicles, especially automobiles. It has for its object primarily a ventilator that can be installed on an automobile 'body that has not been originally designed fora ventilator.

The frame of the ventilator is designed to act as a jig to'aid in the installation of of the car or any Furthermore, this frame isdesigned to support the lever and the locking devices by i which the lever can be adjusted to various positions foropening of the ventilator lid. These, features will more fully appear in the description following.

In the drawings,-

Fig. 1 is a perspective showing 'how the ventilator frame is temporaril bolted to jig in drilling the bolt holes and in 'cutting'out the cowl.

Fig. 2 is aside'elevation; of. thecowl, fra'gmentar in character, showing the ventilator in p ace.

Fig. 3 is a fragmentary vertical cross Sec-,

tion .through the'cowl' and the ventilator.. Fig. 4 is a fragmentary longitudinal section through the cowl and a portion of the ventilator, taken on the line 4-4of Fig. 3.

a designates the usual cowl of an automobile :body.- This cowl is usually curved.

Therefore, it is desirable that the flanges I) and c of the ventilator frame be slightly flexible topermit the frame to adjust itself to cowls having curves of slightly differing radii. The cowl frame is made up of a pair of angle frames which may be stamped out of 'a single piece or may be several stamped 'ieces united, or for that matter," they mig t be castings, but of course, then thefianges would notbe flexible. The upper frame is provided with a pair of knuckles d, (1 adapted to take the hinge in e which hinges the stamped metal 11 f thereto.

to place the same.

.supporting plate 7' at p and a Either before the lid is secured. to the frame or after the same is secured to the frame and turned back the upper and lower frames may be bolted to the cowl, as shown in Fig. 1, lbysimply making two separated holes through the cowl and placing the end bolts h, for instance, in place. This temporar ly makes a jig out of the two frames which acts both as a drill jig and a cutting jig. g designates a drill being used to drill holesvwi-th the two frames used as a. jig. When these holes have been cut the remaining bolts and nuts may be put in place and the metal enclosed in the frame, or a saw,

but it will be found easier to do it with a cold chisel.

An additional function of the lower .frame is to carry the operating lever z.

One end of the lower frame has a depending supporting plate 7', to which this lever may be bolted as at is after the metal in the cowl has been cut away. The load end of the lever has a link m riveted to it and this may be bolted as'at n to the clip 0 on the bottom of the ventilator lid 7.

. A pivoted segment may be bolted to the ull spring 9 attached to the opposite end 0 the segment and also to a hole through the supporting plate This-is. a toothed segment and it passes through a slot 1" in the lever. The teeth have gradual slopes so that by simply swinging the lever the segment is forced down against the spring action of the spring 9 to permit the opening and closing of the ventilator. However, the weight of the ventilato'r acting back through the lever is not sufficient to force the segment down against olding device is both efi'ective and cheap' to manufacture and makes a very easy device to installon the ventilator frame after the frame has done its work as a jig.

What we claim is: 1. A ventilator forinstallation on a sheet metal, structure, having in combination, an upper frame and a lower frame w th central openings in which the inside outhnes of the frames register whereby the frames-can be bolted together on opposite sides of the sheet as a closure for the upper frame.

2. A ventilator for installation on a sheet metal structure, having in combination, an upper frame and a lower irame with central openings in which the inside. outlines of the frames register whereby the frames can be bolted together to act as a jig in cutting out the sheet metal clamped between the two frames, a lid pivoted to the upper frame, and an operating and holding device secured to the lower frame and the operating device also to the lid.

3. A ventilator for installation on a sheet metal structure, having in combination, a pair of frames having accurately registering central openings and that can be bolted on opposite sides of the sheet metal to act as a drill 'ig and a cutting jig in removing a part of the sheet metal, a lid hinged to the upper frame, and an operating and holding means supported on the lower frame and connected to the lid.

, 4. A ventilator for installation on a sheet metal structure, having in combination, an upper frame and a lower frame having central openings with registering boundaries and that can be bolted to opposite sides of the sheet metal to act as a jig to facilitate the removal ofla portion of the sheet metal, a lid hinged to the upper frame, and an operating and holdin device detachably secured to the lower ame and the operating member of which may be detachably secured to the lid after the metal has been removed.

'5. A ventilator for installation on a sheet metal structure, having in combination, a pair of frames that may be bolted to opposite sides of the sheet metal to act as in removing the sheet metal for the ventilating opening, and an operating lever and segment detachably secured to the lower frame and said lever connected with the lid of the ventilator.

6. A ventilator,

having in combination, a palr of frames that may be bolted together,

the under frame provided with a depending.

supporting plate, a lid hinged to the upper frame, an operating lever pivoted to said supporting plate and connected with the 11d, and means supported on said supporting plate by which the operating lever may be held in various positions ofad'ustment.
